als Glabellar Punkt zum Ausgangspunkt der Glabella-Inion-Linie zu machen 
und dies kann natfirlich nur der Gipfelpunkt der Glabellacurve sein, 
welcher den weitesten vertikalen Abstand von der Verbindungslinie NA 
zwischen Nasion (N) und den oberen Ende der Glabellacurve (A) besitzt. 
Dieser Punkt bezeichnet also das vordere Ende der Glabella-Inion-Linie.” 
It is in this way that the glabellar point has been determined in the 
present work. The glabellar chord is drawn from the nasion to the 
junction of the glabellar and cerebral parts of the os frontale, and the

glabellar point is the point on the curve of the pars glabellaris which is- 
farthest away from the glabellar chord. (See fig. 1.) 
In the Tasmanian crania the difficulty in defining the glabellar point 
consists in the fact that it is not easy to separate off the glabellar part of 
the os frontale from its cerebral part, that is, to determine the upper end 
of the glabellar chord. A glance at column 20 of Table XXIX., which 
sets forth the relative positions of the crania compared for the glabellar-
